GRAPPLING-HOOK.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed June 12, 1914. Serial N 0. 844,787.

T all whom it may concern Be it known that I, FRANK N. CANULETTE, acitizen of the United States, residing at the village of Slidell, in theparish of St. Tammany and State of Louisiana, have invented certain newand useful Improvements in Grappling-Hooks, of which the following is aspecification.

This invention relates to grappling hooks.

The object of this invention is the provision of a grappling hookprovided with slidable prongs adapted to be moved to and from the objectto be lifted.

Another object of this invention is the provision of a grappling hookcomprising a plurality of spaced supporting bars and means for slidablyattaching grappling prongs to said supporting bars.

A further object of this invention is the provision of a grappling hookembodying a plurality of oppositely disposed grappling prongs and meansfor moving said prongs to and from each other.

A still further object of this invention is the provision of a device ofthe character described, which will be comparatively simple andinexpensive to manufacture, reliable and efficient in use, and readilyoperated.

WVith the above and other objects in view, this invention resides in thenovel features of construction, formations, combinations, andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of my im proved grappling hook. Fig. 2 is anend view thereof. Fig. 2 is a fragmentary view illustrating means foroperating the grappling prongs. Fig. 3 is a fragmentary detail sideelevation of one of the grappling prongs and the mounting therefor. Fig.1 is a detail transverse sectional view taken on the line aam of Fig. 3.

Referring to the accompanying drawings by similar characters ofreference throughout the several views, the numeral 5 denotes in generalmy improved grappling hook which consists of the spaced parallel endbars 6 formed preferably from channel iron and connected by parallelouter supporting bars 7, and inner supporting bars 8. These supportingbars 7 and 8 are connected to the end bars 6 by the brackets 9, throughwhich fastenings 11 are inserted for rigidly atof the said cables 24:and 25.

taching said brackets 9 to the bars 6, 7 and 8.

A plurality of spaced parallel supplemental bars 12 eXtend between thebefore described end bars 6 and are arranged in pairs, as clearly shownin Figs. 1 and 2 of the drawings. The ends of these bars 12 areconnected by the attaching plates 13 through which fasteners 14: arepassed to secure the said bars 13 rigidly to the upper horizontalflanges of the bars 6.

U-shaped slides 15 engage the under and side edges of the bars 7 and 8and support the shanks 16 of the grappling prongs 17. These grapplingprongs 17 are provided with inwardly projecting terminals 18 designed toengage the article to be lifted. As clearly shown in the figures of thedrawings these grappling prongs 17 are arranged in confronting pairs andare slidable at one end of the grappling hook 5 upon the outer bars 7,and at the opposite end, upon the inner bars 8.

U-shaped bolts 19 surround the shank 16 of the prongs 17 and the bars 7and 3, together with the sliding member 15, and pass through aperturesformed in the opposite edges of the plates 20, to which they areconnected by nuts or other suitable fastening devices, such as shown at21. The prongs at the opposite ends of the grappling hook 5 areconnected by the transverse rods 22 and 23, respectively, and to theserods 22 and 23 are connected the inwardly extending flexible cables 24and outwardly extending flexible cables 25. The cables 21 pass over theinner pulleys 26 journaled between the before-described supplementalbars 12, while the cables 25 pass over the outer pulleys 27 which aremounted in brackets 28 secured, as clearly shown in Figs. 1 and 2,within the channels of the end bars 6. The pulleys 26 and 27 arepositioned and arranged at such angles that the cables 25 will meet at acommon point 29, while the cables 24: will meet at a correspondingcommon point 30, at which points the cables 31 and 32 are attached tothe ends These cables 31 and 32 pass over the pulleys 33 and 34,respectively, journaled upon the derrick arm 35, from whence they passto the drum 36, upon which they are oppositely wound. The drum 36 iskeyed to the supporting drive shaft 37, journaled in the brackets 38carried by a support 39.

The operation of the device is as follows: As the drum 36 is rotated,through any suitable source of power, in the direction of the arrow,shown in Fig. 2 tension will be exerted upon the cables 24, which drawsthe rods 22 and 23 inwardly and, consequently, the pointed terminals 18of the prongs 17 into engagement with the object to be lifted. Thederrick arm 35 can then be swung in any preferred manner to deposit thearticle engaged by the prongs 17, at the desired 10- cality. The drum36' can then be rotated in a reverse direction which draws the rods 22and 23 outwardly through the medium of the cables 25, consequentlymoving the prongs 17 outwardly, releasing the article engaged thereby,and permitting the grappling hook 5 to be again used as previouslydescribed.

It should be understood in this connection that various minor changes inthe specific details of construction can be resorted to within the scopeof the appended claims without departing from or sacrificing any of theadvantages of the invention.

What isclaimed is:

1. In a grappling hook such as described, I

a plurality of supporting members, slides movable upon the supportingmembers, prongs carried by the slides and movable therewith to and fromeach other, rods connecting certain of said prongs, and means engagingsaid rods for forcing the prongs and slides to and from each other.

2. In a grappling hook such as described, a plurality of supportingmembers, U- shaped slides movable upon said supporting members, prongscarried by the slides, bars connecting certain of said prongs, and meansfor moving said bars to and from each other and moving the prongs toengage or disengage an article to be lifted.

3. In a grappling hook such. as described, end bars, supporting barsconnecting said end bars, U-shaped slides upon the supporting bars,means for movably attaching said slides to the supporting bars,grappling prongs carried by the slides, rods connecting certain of saidgrappling prongs, and means for operating the rods to move the grapplingprongs to and from each other.

4. In a grappling hook such as described, a pair of spaced end bars,supporting bars connecting said end bars, U-shaped slides movable uponsaid supporting bars, shanks connected to said U-shaped slides,grappling prongs carried by said shanks, said grappling prongs beingdisposed at the opposite ends of the grappling hook, said prongs at theopposite ends of the grappling hook bolts surrounding the shanks andU-shaped slides, and connected to the plates, the prongs upon oppositeends of the grappling hook being curved inwardly, rods connecting theprongs at each end of the grappling hook, cables attached to said rods,certain of said cables extending inwardly and the remainder of thecables extending outwardly, said inwardly extending cables being united,and said outwardly extending cables being united, and operating cablesattached to the united ends of the before-mentioned cables.

6. In a grappling hook such as described, a pair of channeled endmembers, supporting bars engaging said end members,

' brackets rigidly connecting the supporting bars and end members,intermediate bars connecting said end members, pulleys journaled in saidintermediate bars, pulleys mounted upon said end members, U-shapedmembers slidable upon the supporting bars, shanks engaging the U-shapedmembers, plates engaging the U-shaped members upon opposite sides of thesupporting bars, U- bolts connecting the shanks, U-shaped slides andplates slidably upon the supporting members, inwardly curved prongsformed upon the shanks, said prongs at opposite endsof the grapplinghook being curved inwardly, rods connecting the prongs at the oppositeends of the grappling hook, III-7. 'wardly extending cables connected'tosaid rods and passing over the inner pulleys, out- 7 war'dly extendingcables connected to said rods and passing over the outer pulleys, said 7inwardly extending cables being united and said outwardly extendingcables being united, a rotatable drum, and cables wound in oppositedirections upon saiddrum and connected to the united ends of thefirstmentioned cables.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
